Performing a mounting correction (offset)
The mounting correction corrects a zero offset in the output signal by defining a new
zero point. The zero offset is caused by the mounting position.
Correction range:
±20 % of maximum measuring range
Required tool:
Multimeter (ammeter)
1.
Screw off the case head cover and pull out the push-on cap.
2.
Press [Zero] for approx. 2 s (e.g. with measuring tip of a multimeter).

Mounting correction unsuccessful: Control diode blinks 5 times.
3. Check the output signal as follows.
CAUTION!
Incorrect connection.
A short circuit will destroy the process transmitter.
- Ensure that the multimeter does not come into contact with the positive
power supply terminal.
